ABSTRACT
The nautilus shell is an example of the synthesis between form and function found in nature. Its form is the result of evolution, which is both transparent and beautiful. The nautilus shell is a perfect analogy for design and the design process because it creates valuable user experiences and usable interfaces. The challenge presented to a design team is to plan a prototype with a clear purpose that is easy to use, meets user needs, addresses commercial considerations, and can be mass-produced. Its visual form, whether two- or three-dimensional, digital or analog, logically explains its purpose and efficiently leads the user through its function. Visual design decisions are based on project goals, user perspective, and informed decision making. While many aspects of design are quantifiable, there are visual principles that are less measurable but equally important. Even though the necessary skills to become visually literate and make competent design decisions can be learned, design involves a highly specialized knowledge base.
